Abstract (en)

[origin: EP1235224A2] A disk unit (11), such as a magnetic disk unit, has a temperature sensor (21), a humidity sensor (22), a heater (27) and a Peltier element (24). The disk unit (11) is heated and cooled in accordance with sensed temperature and humidity. The disk unit (11) further has a double-structure housing comprising a first inner housing (31) and a second outer housing (41) surrounding the first housing (31), so that an internal environment wherein the disk unit (11) is located, is isolated from an external environment outside the second housing (41). <IMAGE>
